To all whom it may concern.' h

Be it knownl that I, JAY HUGHES, a citizen of the United States, residing at Atkinson, in the county of Holt and State of Nebraska, have invented certain new and useful Improvements in Road-Scrapers; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in a road scraper and has for one ofits objects the .provision of a device of this character, which is especially adapted for removing the dirt from the sides of a road anddepositing the same in the center thereof, which gives the correct grading to each side thereof.

Anotherv object of this invention is the provision of a pair of frames' arranged in parallelism with each other so that the scraping means carried thereby will carry and deposit the dirt from the sides of the road on to the center thereof.

A further object of this invention is to provide means for permitting the frames to be moved toward and from each other as desired, so as to regulate the point of the sides of the `road thatlthe dirt is to be removed from.

A further object of this invention is the provision of diagonally arranged scraper blades on each of the frames for cutting and carrying the dirt from the sides of the road to the center thereof.

A further object of this invention is the provision o f means for raising and lowering the frames for engaging and disengagin'g the scraper blades with the ground and also regulating the 'depth of the cutting action of said blades.

A further object of this invention is the provision of a plurality ofdiagonally arranged colters positioned forwardly of the scraper blades for cutting the ground and trash that may accumulate under the frames.

A still further object of this invention is the provision of' means for raising and lowering the colters with relation to the frames, whereby the cutting action thereof may be regulated.

A further object of vthis invention is to rovide cushioning means between the rames, which will absorb shocks to the Specification of Letters Patent.

frames and aid in preventing them from moving out of parallelism with each other.

A still further object of this invention isl the provision of a road scraper of the above stated character, which shall be simple, durable and eflicient, and which may be manufactured and sold at a comparatively low cost.

will become more apparent as the description proceeds, the invention consists 1n certain novel features ofv construction, combination and varrangement of parts as will.

be .hereinafter more fully described and claimed.

For a complete understanding of my in-l vention, reference is to be had to the following description and accompanying'drawings, inwhich Figure 1 is a top planview of a road With these and other objects in View as 'scraper constructed in accordance with my Fig. 7 is a longitudinal sectional view of i the cusl'iioning means,

' Fig. l8 is a transverse the same,

Fig. 9 is a. fragmentary sectional view of one ofthe means for raising and lowering the frames, l i

Fig. 10 is a. fragmentary vertical sectional view of the means for adjusting the colters and furnishing the journals thereof with lubricant,

Fig. 11 is a detail view illustrating a pawl and ratchet mechanism employed for raising and lowering the frames,

Fig. 12 is a fragmentary side-elevation illustrating the openings in one of the side members of the frame to permit the dirt to pass outwardly of the frame.

sectional view of Referring to the drawings in detaihthe numerals l and '2 indicate frames, which -are arrangedv in parallelism with each bther BEST AVAlLABLE COF" are arranged slightly in advance of the inner side members andl are connected by diagonally arranged beams 5, 6 and 7 to to pass outwardly between the inner side members 3 of the frames 1 and 2. Draft chains 10 are connected to the forward ends of the frames 1 and 2 so that the device may be readily connected to a draft power.

A plurality of diagonally arranged-supporting members 11 are secured to the frames 1 and 2 and slidably mounted therein are pairs of hollow supporting rods 12, which have secured to their lower ends, journals 13. The journals 13 are slidably supported in substantially U-shaped brackets 14 carried by the inner and outer side members 3 and e and the longitudinal bracing members 15, which are secured to the diagonally arranged beams -5 and 6. The journals 13 have rotatably mounted therein, shafts 16 on which are mounted, a plurality of colters or cutting disks 17, the colters or cutting disks 17 being spaced apart by blocks 18. The shafts 16 are supported diagonally of the frames and one in front of the other as clearly shown in Fig. 6. 'lhe hollow rods 12 are externally screwthreaded and have threaded thereoaadjusting nuts' '18', whereby the rods may be raised and lowered for regulating the cutting action of the disks. Secured to the upper ends ot' the hollow rods l2 are grease cupsv19 for the purpose of furnishing the journals 13 with lubricant. (oiled springs 20 are mounted upon the rods 12 for normally urging the journals downwardly with relation to the trames 2 and 1, thus it will be seen that by threading the nuts 1S upon the rods l2 in a cldakwise direction, the colters or cutting dslts 17 will be raised.

A plurality ot transversely extending bracing strips 21 are carried by the side members il and 4 of the trames 1 and 2; the

'strip A constituting one of the strips 21 upon the `trarne has journaled therein a rod to which is secured a cable 223 that extends through the inner side members 3 ot' the trame 2 and is secured to the inner side members 3 ot the frame 1. A similar rod 2li is journaled in one of the members 11 of the trame 2 and has connected thereto, a cable 25. which is secured to the inner side members 3 or' the frame 1. Each of the rods 22 and 24 have secured thereto, handles 26 a5 for rotating said rods to Wind the cables 23 and 25 thereon for moving the frames 1 and 2 in the direction of each other. Each of the rods and 21 have secured thereto, ratchet gears 27, which are engaged by spring actuated dogs 28 for preventing the rods 22 and 24 from rotating in a reverse direction, whereby the t' 'ames 1 and 2 may he adjusted in relation to each' other and held in any desired adjusted position.

Secured to the corners of each of the trames 1 and 2 are supporting structures S0 constructed from angle iron members 31. which are secured to the frames 1 and 2 as shown at and have secured in their upper ends, guide blocks The guide blocks 33 are apertured to slidably receive a rod 34C, which extends through the frames l and 2 and have swiveled to their lower ends, rollers Pairs of relatively spaced housings Sti are located withm the supporting structures 30 and have journaled therein, rollers 257. Positioned between the housings B6 and surrounding the rods 34 are coiled springs 88, which bear against bloclts 89 carried by the rods. The blocks 3.) have connected thereto. cables 40, which extend through apertures in the tops of the housings 3G and pass about the rollers 3l'. The cables after passing about the rollers 23T are secured to rods il, which are journaled in the lrames l and 2 and in reinforcing members 12%. 'lhe rods il have connected thereto, handles ll and also ratchet wheels l5, similar to the ratchet wheels 27, which are engaged by spring actuated dogs 46. liy rotatinglr the rods #l1 by the handles 41 winding the cables 40 thereon, the cables draw the blocks 3S) downwardly, moving the wheels 35 in engagement with the ground and elevating the trames l and 2, thus it will be seen that any corners or the entire trames may be elevated when desired so as io engage and disengaa'c the scraper blades 8 and cutters trom engagement with the ground to render the device operative and inoperaiive when desired.

livotally secured to the 'front ends of the outer side members l oi the trames 1 and2 are substantially U-shaped arms 4l' to which are. secured rods iS on which are journaled rollers 4f). llxtensions 5() are secured to the ends of the side` members 4 of the trames 1 and 2 and overlie the arms l17, and have mounted therein, rods 5l, which are secured to blocks 52 that. are in turn secured to the arms 47. Adjusting nuts 53 are threaded to the rods Ylor raising and lowering the arms Ii7 to engage and discngage the rollers 19 from engagen'ient with the ground.

(oiled springs 5-1- are positioned upon the rods 51 between the extensions 5() of the arms 47 vt'or normally urging said arms downwardly. The rods i8 to which the rollers 49 are journaled are swivelly coni are constructed 4from a pair of channel bars 56.v The channel bars` 56 are connected together by a pluralit of relatively spaced rectangular blocks 5 The fastening elements 58 pass through apertures 59 in a pair of the blocks 57, for securing theconnect- I ing members 55 to the frames 1 and 2. The Vblocks that receive the fastening elements 58 have connected thereto, rods y6.0, which are slidably received within the adjacent block 57 and on which are mounted coiled ksprings 6l for the purpose of cushioningly supporting the block 57 that receives thev fastening elements r58, whereby shock absorbing means is provided' between the frames l an'd 2 and which construction will permit the frames 1 and 2 to be moved toward and from each other as desired.

In operation, a suitable draft power is connected to the chains 50 and the frames l and 2 are adjusted from each other to the desired point so as to make the device operable upon each side of the road and by forward movement of the frames `1 and 2,

the Scrapers cut into the ground and carry the loose dirt to the center of the road. The cutters or colters 18 cut into the ground4 and loosen the same, making it easy for the Scrapers to deposit the loose dirt into the center of the road. j

By rotating the rods 41 the rollers 35 may be moved into engagement with the ground for disengaging the cutters and Scrapers from the ground so that the device may be conveyed from one'point to another in an inoperative state.

While I have shown and described the preferred embodiment of my invention, it will be understood that minorchanges in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

l. AA road `scraper comprisinga pair of frames, flexible `means connecting said frames, means connected to said flexible means for movmg said frames toward and from each other, shock absorbing means connecting said frame,` and cutting means carried by said frames.
